Blackfin stingray [2] ( lat. Fenestraja atripinna ) is a species of cartilaginous fish of the rhombus family of the rays of the stingrays. They live in the central-western part of the Atlantic Ocean . They are found at a depth of up to 951 m. Their large, flattened pectoral fins form a heart-shaped disk with rounded edges. The maximum recorded length is 29 cm. Eggs are laid. They are not the target fishing target [3] [1] [4] .

The species was first scientifically described in 1950 as Breviraja atripinna [5] . Species epithet comes from the words lat. atri - “black” and pinna - “feather”, “wing”, “fin”.
These bathydemersal slopes live in the central west Atlantic off the coast of North Carolina , southern Florida, in the waters of the Bahamas and Cuba . They are found on the continental slope at a depth of 366 to 951 m [1] .
The wide and flat pectoral fins of these slopes form a heart-shaped disc with a slightly protruding snout tip and rounded edges. On the ventral side of the disc are 5 gill slits, nostrils and mouth. On the long tail there are lateral folds. These skates have 2 reduced dorsal fins and a reduced caudal fin [3] .
Rostral cartilage is elongated. Dorsal fins are located at a fairly large distance from each other. The dorsal surface of the disc is pale pinkish-brown in color without noticeable marks. The ventral surface is even whitish, covered with chocolate brown spots with blurred borders with age [6] . The maximum recorded length is 29 cm [1] .
Like other rhombic, these stingrays lay eggs enclosed in a rigid horn capsule with protrusions at the ends [1] .
These skates are not subject to targeted fishing. Potentially by- catch . The data for the assessment of the conservation status of the species by the International Union for Conservation of Nature are insufficient [1] .
